I have just stopped opera, loaded the file from my original laptop SSD drive, as the adaptor has just arrived (rather than the backup I used, made the day the laptop expired), restarted and checked the bookmarks again. Now, under 'other bookmarks' is a folder with my old laptop id which has the speed dial entries in. Must be a problem with the backup, as the one on the drive seems to work. Thanks for your help.

After a bit of tinkering I managed to fix my speed dial page. But after restarting my PC and Opera, I find the speed dial page empty again. I thus exported the speed dial bookmarks to html from another PC with Opera, and I copied this file to my PC to import it.

This is the result :

SM-a528B is my smartphone bookmark;
Desktop-5MPD2F5 is the bookmark from my first attempt, emptied by hand;
Desktop-5MPD2F5 is the bookmark of my second attempt, made with your help and now empty, because I had moved all the links to the Accesso Rapido root (speed dial);
Desktop-U0BRSGH is the bookmarks imported from the second PC.

I could move the links again by hand as I did yesterday but since I find, from all the tests done, a series of old bookmarks imported by mistake in the previous days, I think I will uninstall Opera and all the data, to try to import again that HTML file from second PC

@dragoncat I'm not sure if it's possible.

@shackleton If the option is there and it's enabled, then the option still exists. I would try with a clean profile to see if it helps.

Do a backup by exporting your favorites to a html file, then if problem occurs, re-import them.
